Precaution for CAN Communication System
WARNING: This page is about a different car, the 2004 Suzuki XL-7 and 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
The looseness in the wire harnesses' twist of the CAN lines except around the connector should be within 100 mm (3.9 in.). Excessively loose lines may be influenced by electric noise. Do not connect terminals of the CAN line using a bypass wire. Otherwise, the CAN line may be influenced by electric noise.
